There's no way to send the array "as-is" through a socket. You will have to do it the hard way -- sorry!
What I recommend is you first send the number of elements in the array, then loop through the array sending each element.
If the array is of complex types (i.e. not just integers), you will have to make sure you and the other end agree exactly as to the layout of the data.
Note that sending floating-point numbers can be a problem, so you'll have to convert them to fixed-length strings before sending them. You can't just convert them to ordinary strings, since they would be of varying length and the other end wouldn't know how much data to receive.
Same applies to strings in general -- the other end has to know how much data to expect, so for each string, you'd have to either send the length in advance (as an integer!), or send only fixed-length strings.
Oh, and if the other end of the connection isn't running on an Intel CPU, you might have problems with big-endian vs. little-endian numbers. Intel CPUs store numbers in reversed format, and other CPUs store them the other direction. If this is the case, you'll have to send numbers as fixed-length text as well. This is the big problem that XML solves. But for a game, XML would be too wordy and would slow things down too much.
What you might want to do is examine some of the source code that id (Doom, etc) has released. There's some networking code in there somewhere. You'll see that they're doing all of the above, plus more to shrink the size of their network packets.
Hope this helps.
